SWING keyboard events

[Haider Kazmi]

Need a nudge in the right direction

Is there a way to get the keyboard events from the entire UI without adding
keyboard adapters to every component on the Frame.

Your topmost frame (or the current active window if you have multiple
native windows/frames/dialogs) is where these events first arrive from
the native windowing system. Overriding the processKeyEvent method of
these JFrames / JDialogs/ JWindows will allow you to have a first look
at the event. (Don't forget to call super.processKeyEvent method to
dispatch it normally if you aren't handling it).

By the way, if you're using swing, KeyListeners aren't normally the
right approach. Take a look at the InputMap/ActionMap architecture.

Yes, but I'm at home now and don't have the code. There are options for the
current window, and all sub-Windows, etc. Please search in java.sun.com
